review text: \textit{A. Broer} [Prog. Math. 123, 1-19 (1994; Zbl 0855.22015)] proved that over a field of characteristic zero subregular nilpotent varieties are normal. One of the main ingredients in the proof is a vanishing result concerning line bundles on the cotangent bundle of a flag variety. In the present article the vanishing and normality results of Broer are generalized to positive good characteristics.
